Turriviridae
Turriviridae is a family of viruses; it contains only one genus, Alphaturrivirus. The archaea Sulfolobus solfataricus serve as natural hosts. There are two species in the genus Alphaturrivirus.
Taxonomy
The genus contains the following species, listed by scientific name and followed by the exemplar virus of the species:- Alphaturrivirus hveragerdiense, Sulfolobus turreted icosahedral virus 2
- Alphaturrivirus yellowstonense, Sulfolobus turreted icosahedral virus 1
Structure
Viruses in Turriviridae have icosahedral geometries, and T=31 symmetry. The diameter is around 74 nm. Genomes are circular.| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
| Alphaturrivirus | Icosahedral | T=31 | Linear |
Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by adsorption into the host cell. DNA-templated transcription is the method of transcription. Sulfolobus solfataricus serves as the natural host. Transmission routes are passive diffusion.| Genus | Host details | Tissue tropism | Entry details | Release details | Replication site | Assembly site | Transmission |
| Alphaturrivirus | Sulfolobus solfataricus | - | Injection | Budding | Cytoplasm | Cytoplasm | Passive Diffusion |
